理解章节样式代码

Question

我想为我的报告找一种奇特的风格，我在网上找到了一个这里

我将其用于另一份报告，但代码并不完全相同。我想尝试一下，更改一些东西，然后开始意识到我上次（太久以前了）对它做了太多改动，以至于我不能再使用它了。

现在，在新电脑上，在新项目上，我想开始一种新的风格，并且想尝试一下这种风格的元素。

唯一的问题是，首先，我可以像示例 (n°39) 那样让它工作：我不明白黑匣子。其次，我不太理解代码。

这就是为什么我寻求您的智慧，翻译这段代码，以便我可以使用它。

这是我的代码：

\documentclass[12pt]{report}

\usepackage[utf8]{inputenc}
\usepackage[english]{babel}
\usepackage[top=2cm, bottom=2cm, left=1.5cm, right=1.5cm]{geometry}
\usepackage{fancyhdr} % En-têtes et pieds de page
\usepackage{psboxit,pstricks}

\makeatletter
\renewcommand\part{%
  \thispagestyle{fancy}%
  \if@twocolumn
    \onecolumn
    \@tempswatrue
  \else
    \@tempswafalse
  \fi
  \null\vfil
  \secdef\@part\@spart}

\renewcommand\chapter{
  \thispagestyle{fancy}%
  \global\@topnum\z@

  \secdef\@chapter\@schapter}

编辑 ：

正如 Christian Hupfer 所说，我的代码无法正常工作，可能是因为 psboxit 和 psboxtricks 软件包太旧了

这是我以前使用过的代码，但我在没有真正理解它的情况下对其进行了修改：
